Dom-jot was a game played with a ball and cue on a table with an irregular geometric coordination, similar to Terranbilliards with certain elements of pinball. Rolling the terik into straight nines was considered an extremely skilled move in dom-jot.

While standing in Jake and Nog's customary spot above the Promenade and watching the incoming passengers, Jake was feeling lonely while Nog was away at the Academy. In defense of Nog's decision to join Starfleet, however, and despite his feelings, Jake told Quark that he was proud of what Nog was doing. Quark replied, "Remember that the next time you try to play dom-jot by yourself." (DS9: "Shattered Mirror")

Several dom-jot balls, described as "acrylic spheres about the size of a billiards ball, in quasi-transparent colors with a diameter of approximately two inches", were later sold off in the It's A Wrap! sale and auction for $565.55. [2]

Just prior to the Attrexian space station mission in the non-canon video game Star Trek: Elite Force II, Ensigns Jonathan Struhlem and Brian Bobowski can be overheard discussing dom-jot in the shuttlebay of the USS Enterprise-E. Following the death of Ensign Franklin in the previous mission, Struhlem states he would miss their regular dom-jot sessions, to which Bobowski replies that he never understood the game, and prefers poker instead.
